Abstract :
A reconfigurable CT 5th-order 1b ΔΣ modulator is presented. The DR/BW is programmable from 85dB@100kHz to 52dB@10MHz in 121 steps. Implemented in a 90nm CMOS process, the 0.36mm 2 IC includes 2 ΔΣ modulators, a bandgap reference, and a decimator. The power consumption of a single ADC in different modes ranges from 1.44 to 7mW at 1.2V supply
